Abstract

An ozonesonde for in-situ measurement of stratospheric ozone concentration profiles by balloon launches includes a hydrothermal buffer having a vessel surrounding a measurement cell having an aqueous reaction solution. The aqueous reaction solution has melting and boiling points dependent on a salt content. A pump is configured to pass ambient air through the aqueous reaction solution. The vessel of the hydrothermal buffer is fillable with water to a level that is at least as high as a level of the aqueous reaction solution in the measurement cell. A melting point of the water is higher than the melting point of the aqueous reaction solution and a boiling point of the water is lower than the boiling point of the aqueous reaction solution so that a temperature in the measurement cell is stabilized between the melting point and the boiling point of the aqueous reaction solution, upon the ozonesonde reaching the stratosphere, by a transfer of energy to or from the aqueous reaction solution in a thermodynamically passive process in an earlier phase transition of the water before a reaching of a triple point of the water.
